LED lighting

LED Lighting

Program overview

At present, if constant DC power supply is adopted for LED lighting lamps, which are more and more widely used, it is theoretically possible to achieve constant lighting without stroboscopic. But in fact, due to the lack of industry standards, the market competition is fierce and disordered, and the market is full of low-quality LED lamps, especially indoor low-power LED lamps, which also have stroboscopic problems. In order to obtain a pure constant current source, the LED driving power supply is the key to ensure that the LED lamp does not flash. At present, LED power supply can fully meet the requirements of no stroboscopic.
